Q. There are

650

students in the graduating class at East Community College. Of these students,

48\%

plan to attend graduation and

44\%

don't plan to attend. The rest have not decided. How many students are not sure they will attend?

Calculate Attendance Number: Calculate the number of students who plan to attend graduation. $\newline$ To find the number of students who plan to attend, multiply the total number of students by the percentage that plan to attend. $\newline$ Number of students planning to attend $=$ Total number of students $\times$ Percentage planning to attend (as a decimal) $\newline$ Number of students planning to attend $= 650 \times 0.48$
Calculate Attendance Number: Perform the calculation for the number of students planning to attend. $\newline$ Number of students planning to attend = $650 \times 0.48 = 312$
Calculate Non-Attendance Number: Calculate the number of students who do not plan to attend graduation. $\newline$ To find the number of students who do not plan to attend, multiply the total number of students by the percentage that do not plan to attend. $\newline$ Number of students not planning to attend $=$ Total number of students $\times$ Percentage not planning to attend (as a decimal) $\newline$ Number of students not planning to attend $= 650 \times 0.44$
Calculate Non-Attendance Number: Perform the calculation for the number of students not planning to attend. $\newline$ Number of students not planning to attend = $650 \times 0.44 = 286$
Calculate Undecided Number: Calculate the number of students who have not decided if they will attend. $\newline$ To find the number of undecided students, subtract the number of students planning to attend and the number not planning to attend from the total number of students. $\newline$ Number of undecided students = Total number of students - (Number of students planning to attend + Number of students not planning to attend) $\newline$ Number of undecided students = $650 - (312 + 286)$
Calculate Undecided Number: Perform the calculation for the number of undecided students. $\newline$ Number of undecided students = $650 - (312 + 286) = 650 - 598 = 52$
